not sure how it is that I am the first to review this but here I am! I bought my master series vacuum bottle 3 or 4 years ago and use it EVERY day. it is a massive upgrade to there classic coffee thermos which I had before, particularly when it comes to the pour thru cap, it works perfectly and doesnt spill coffee all over the truck when I want to pour a cup one the road, also the cup itself is a huge upgrade to the classic, the classic (green bottle) had a plastic cup with a thin metal skin, it burns your hand and then gets cold very fast, this one has a somewhat insulated all metal cup with a nice rubber bottom. it I very nice! I lost the cup TWICE and stanely sent me a new one TWICE no questions asked no shipping fee just sent me a new one. I highly recommend this item. also has some coating on it that makes it super durable. mine still literally looks brand new even though its been used and abused. for those of you who like there stuiff to stay looking nice? this will do for you, I can wash it off and after 4 years of daily use on construction sties getting dropped and everything else it looks sleek and new still. price seemed high but now I wouldn't blink an eye to spend it again if I lost mine, its worth it 100%

Bulky and heavy. But worth it for a solid performer. Mug/lid hold heat and cold very well AND a soda can fits in there nicely if you want to insulate a caned beverage.

I'd really like it if there was an alternate stopper for the top with a flip pour spout. I need precision pouring and it's hard to control or predict the flow of water. I tend to pour hot water into a narrow location and it sucks to get hot water in your lap or hand. If your pouring into a coffee cup, I'm sure you'd have no complaints.
This type of pour spout also makes it nearly impossible to sip directly from the container, though with something this bulky or heavy, your probably prefer not to.

Ultimately a great purchase as it works very well. It is very solid from head to toe. The handle is VERY sturdy and has a nice thick no slip grip that you can handle with confidence. The finish is very robust. No doubt the whole thing will last a lifetime.

If you need something light weight over something sturdy or something that will outperform the competition then this is not for you.

No regrets as it works better than anything I've tried.
Make a protruding spout stopper and this would be 5 stars.

i have never drank so much water until i had this bottle. it’s 40 oz and i’m constantly sipping all day. the only thing is you have to make sure you clean it and get a straw cover / replacements or else it gets dirty. keeps water cold for so long.

I've had this for about a month now and am pleased with its performance. I have only used it for hot water, it holds water temperatures for a very long time. The bottle and handle seem very sturdy, I have no doubt that it will last a very long time.

The cover doubles as an insulated cup that has a rubber base so that it won't slip, which is a nice touch. My only complaint is the threads on the cover don't meet perfectly to the bottle itself so it takes a bit of effort to get it on and off. Perhaps it will wear in over time, currently it still makes grinding noises when putting it back on.
